In Figures 1 to 3 inclusive, 1 have shown an upstanding stand or frame, comprising upstanding legs 25, arranged in a rectangular group, and converging upwardly. These legs are rigidly connected near their lower ends by horizontal tubes 26, upon which is rigidly mounted a box 21, for holding tools, parts, or the like. The legs 25 are preferably tubular and the lower ends of these tubular legs are internally screw threaded for receiving screw threaded shanks 28 rigidly secured to yokes 29 of caster wheels 36. By turning the screw threaded shanks 28 within the lower ends of the legs 25, these legs may be vertically adjusted, and the shanks 28 are locked in the selected adjusted position by set screws 3|. Rigidly secured to the upper ends of the legs 25 are couplings 32 which are rigidly secured to a horizontal frame 33, including sides 34 and 35 and U-shaped ends 36 and 31. Rigidly secured to the end 36 is a vertical strap 38, the lower end of which is rigidly secured to a horizontal strap 39, in turn rigidly secured to the adjacent legs 25. Guide sleeves 4| and 42, are rigidly secured to the vertical strap 38, and slidably receive a vertical reciprocatory rod 43. The rod 43 extends through the open frame 33 and is rigidly secured to a carriage or tray 44. This carriage or tray is horizontal and is circularly curved in vertical cross section, to provide an upper curved recess, to receive the cylinder of a hydraulic press, to be described.

Rigidly secured to the horizontal strap 39 are verticalears or knuckles 45, receiving between them the head 46 of a forked lever 41. This head is pivotally connected with the knuckles 45 by a pin 41. The forked end of the lever is pivoted to the vertical rod 43 by means of a pin 48, operating within elongated slots 49 formed in the forked end of the lever 47. Pivotally connected with the lever 41, as shown at 50, is a weighted dog for coaction with a stationary generally vertical quadrant 52, the upper end of which is rigidly secured to the U-shaped end 31, as shown at 53. This quadrant has a lower notch 54, an intermediate notch 55, and an upper notch 56,

as shown. The dog 5| is adapted to engage in these notches.

The numeral 51 designates a hydraulic press substantially identical with the hydraulic press shown in my pending application for Hydraulic draft roll press, filed January 3, 1946,. Serial number 638,862. This press includes a horizontal cylinder 58 and a plunger 59, having an opening 60 formed therein and a set screw 6|, leading to the opening. The hydraulic press may be manually operated by a handle 60?. The cylinder 58 is provided at its top with a handle 6|. The cylinder 58 is provided upon its sides with lugs or trunnions 62, for insertion within notches 63 formed in vertical ears 64, formed integral with the carriage or tray 44. When the ears 64 engage the irame 33 they limit the downward movement of the carriage or tray 44. The cylinder is mounted upon and within the carriage or tray 44, and the trunnions 62 are held Within the opening 63, thus preventing the cylinder 56 from moving longitudinally with respect to the carriage or tray.

Several units are applied to and operated by the hydraulic press. The first unit to be described is the straightened unit. This unit, Figures 1, 2, 4, 5, and 6 comprises a horizontal bar 62, having rigid links 63 arranged beneath it and rigidly secured thereto. These links have upwardly oifset ends terminating in horizontal extensions 64. The bar 62 has a recess 65, Figure 6, which is curved in cross section, receiving a cylindrical guide rail 66, rigidly attached to the bar 62 by rivets 66, or the like. The guide rail 66 has its vertical diameter disposed outwardly of the bar 62. Slidably mounted upon the guide rail 66 are jaws 6'1, having vertical V-shaped recesses 68. Ad ustably mounted upon the top 01' the bar 62 is a slide 69, having elongated slots HI, for receiving set screws ll, having screw threaded engagement with the bar The slide may be longitudinally adjusted upon the bar 62 and locked in the selected adjusted position. The slide 69 has a vertical head 22, provided with a transverse groove 13, and a set screw 74 engages the head 72, upon one side of the groove 73. The set screw has a clamping portion 75, projecting over the groove 73, and a washer 16 is preferably arranged beneath the clamping portion 15 and also projects over the groove 73. The groove 73 is adapted to receive a slide 11 which is adjustable therein and clamped in position by the set screw 14. This slide carries a vertical post '11, having a horizontal extension '18, held in an opening 79 of the slide 11, and having a friction fit therein, so that the post 1'! can be adjusted to the vertical position. A guage 19 is provided, having a finger 80, to engage with the assembled draft roller sections or their journals, for determining if the assembled sections are straight. This guage is mounted upon an arm 8|, having a vertical opening 82, to receive the post 11' and the post is clamped in the opening 82 by a set screw 83.

The cylinder 58 is provided with horizontal apertured lugs or knuckles 84, for insertion within the forked ends of rigid links 65, and connected therewith by pins 86, passing through these apertured elements. The opposite ends of the links 85 are forked and these forked ends are apertured to receive the apertured extensions 64 and these apertured elements are connected by pins 81. The links 85 may ordinarily remain attached to the lugs 84, while the links 63 are separated from the links 85, when it is desired to remove the straightening unit. The numeral 88 designates a bending tool, having a shank 89 for insertion within the opening 66, and clamped therein by the set screw 6|.

In Figures 7 to 10 inclusive, I have shown a separating unit, which is substantially identical with the separation unit shown in my said application 638,862. This separating unit comprises a relatively stationary guide 96, which is straight and elongated and formed generally U-shaped in cross section. This guide includes a bottom ill and sides 92, having inwardly extending horizontal flanges 93. The ends of the guide 96 are open. Disposed within the guide 90 are slides or igsdoirde carriages 94, which move in a straight line. At their inner ends, these slides or carriages carry vertical ears or'jaws d5, integral therewith. These jaws have vertical jaws or slots 96, for the reception'of thejeurnals, to be described. The jaws '95 are at right angles to the longitudinal axis of the slides or carriages 9t. At their inner ends, the slides or carriages St are provided at their bottoms with recesses o-r notches 91, forming horizontally inclined faces 98, Figure 9, which convergetransversel-y of the guide 90. One side'92 has an opening 99, and the other side 92 has an opening Iflii. Adapted to be arranged between the inclined facesiit isatapered'expanding element or head i fii, to entert'he openings 93 and I00. This expanding element or head has a shank I'flZ. This shank is adapted for insertion withinthe opening 63 of the plunger 59 and to benlamped therein by the set screw 6 I. One side 90 is provided near its ends with 'aper'tured knuckles I63, for insertion within the forked ends of the links 85, and to be held therein by the pins '31. Rigidlysecured to the knuckles Ili3are stops :IM, having inturned ends I95, to limit the rearward movement of the tapered or expanding element IIII.

.I have, shown an assembling unit in Figures 11 to .14 inclusive, which is substantially identical with the assembling unit shown in my said application 638362. This assembling unit comprises a horizontal housing or guide lat, including a bottom Nil, top I93, .and sides I8 9, Figure .14. One side I09 has openings :i It and the opposite side I09 has openings I I I. The ends of the housing or guide are open, as shown. Mounted to reciprocate within the guide I06 are slides or carriages H2, provided at their ends with clamps II3, integral therewith. Each clamp comprises a lower part H4 and an upper part H5, having semi-cylindrical recesses I I6, which when assembled form a cylindrical recess for receiving the journals, to be described. The upper part II'.5 has wings Ill and the 10Wer part Wings I I3 and these Wings are connected by bolts H9. Thenumeral I designates a forked contracting element or head, including spaced portions or tines I2I, having straight outer edges H22 at right angles to the carriages H2, and inner inclined edges I23 which engage inclined walls I24 of recesses I25 formed in the bottoms of the carriages IIZ. The free ends of the tines .I2I are connected by a bar I242 The contracting element or head I26 is provided with a shank I26, for insertion within the opening 6,5, and to be clamped therein by the set screw BI. The housing or guide I66 is provided at its ends with horizontal rigid arms I21, having apertured knuckles I28 to be inserted within the outer forked ends of the links 58 and held therein by the pins 81.

Attention is now called to Figures 15, 16 and 17.. The numeral I29 designates the roller beam if a spinning frame. Thebearings for the lower draft rollers, and the saddles for the upper draft rollers, and associated elements are omitted. 'The numeral its designates brackets, which are rigidlymounted upon the roller beam I 29, preferably at the meeting ends of the draft roller sections, but may be arranged at other points. Each bracket I38 includes an upstanding shank I3I provided at its top with a generally U-shaped socket 'or head 132, having a copper rib I33 mounted upon the upper face of the fork I32. Thepurpose of this copper rib is to provide a soft "supporting element for the journals, which will not scratch them. The shank ItI is rigidly secured *to a "generally hor'izorital *base 434, the

free end of which is provided with'longitu'dinal slots I35, receiving bolts I36, secured to the roller beam l29. These bolts may be passed'through the openings through which the chains or rods pass, which are connected with the saddles of the upper draft rollers and which carry the usual weights. Rig-idly connected with each base I34is an L-shaped guage or stop I3i, to contact with the front face of the roller beam 29, thus insuring that the several brackets I30 will'be in alignment.

In Figure 15, the numeral I38 designates one ofthe lower draft rollers of the spinning frame which extends for the entire length of the roller beam 18. This draft roller shown as removed from its bearings carried by the draft beam I29 and supported within the sockets I32 of the brackets. This draft roller is ordinarily 30 to 32 feet long. The draft roller I38 is formed in sections I39 and Idil, which are ordinarily 22 inches long. 'The intermediate sections its, Figure .12, are provided-at corresponding ends with cylindrical journals Isl, carrying extensions I42, which are square in cross section, for insertion within the openings or sockets hi3, formed in the corresponding ends of companion sections I39 and the inner ends of the sections ltd. These openings or sockets are also square in cross section and the extensions I42 have a driving fit within the sockets M3. At their outer ends, thesections I59 have the journals I -I, but the extensions Ifl are omitted. The several journals iii are held within the bearings of thespinning frame, which are mounted upon the roller beam G29. Each roller section I55 and Mil, has fluted roller members Ii l, which are spaced, and smooth cylindrical portions Hi5 arranged between the fluted roller members. Atltheir ends, the roller sections I39 and its have smooth cylindrical portionsI-tfi, of larger diameter than the journals IeI, forming shoulders Idl. The journals Eel are held within the draft roller bearings which are mounted upon the roller beam 12s.

The operation of the machine is as follows:

When the lower draft roller sections are to be separated and removed, the saddles carrying the upper draft rollers are removed and laid back on the spinning frame. The lower draft rollers I38 now remain within their bearings, and are uncovered and are now accessible so that either of them can be removed. The brackets we are now rigidly mounted upon th roller beam 529. The selected draft roller I38 is removed from its bearings and supported in the sockets I32 of the brackets I30, at an elevation above the roller beam I29 and forwardly of the same.

The first operation is to separatethe selected draft roller sections, and for the purpose of illu tration, I have shown the separation of thedraft roller sections I39, Figure 15. The separating unit is now applied to the hydraulic press 51 and the lever 41 is swung to the lowermost position so that the dog 5| is beneath the notch 5t and the lugs 64 engage the frame 33. The stand or carriage carrying the hydraulic press is now rolled in proximity to the draft roll I38 supported in the brackets. The jaws should pass beneath the journal I4I of the draft roller sections I39, with a, clearance of about one-eighth to onequarter of an inch. If this clearance is not provided, the frame or stand is vertically adjusted by turning the shanks 28 within the legs 25, .until such clearance is provided, and the shanks are locked in the adjusted position by the set screws 3|. This adjustment will provide suitable clearance for the'other units when applied to the hydraulic press. The stand or frame is then rolled toward the draft roller I38, until the jaws 95 pass beneath the journal MI and the openings 96 are in alignment with this journal, Figure 20. The lever 41 is now moved upwardly so that the dog will enter the second notch 55 from the bottom, and this will raise the jaws 95 so that their openings 96 will receive the journal I. The hydraulic press 51 is now operated so that its plunger 86 moves outwardly and the expanding lement ltll will move forwardly, separating the carriages 94. The jaws 95 engage the shoulders I41, and the extension M2 is withdrawn from the socket I43. The lever I4! is now returned to the lowermost position and the carriage or stand rolled from the draft roller I38. The same operation is repeated for separating the opposite end of the draft roller section I39 from its companion draft roller section I40.

After th journals of the removed draft roller section are repaired, or a new draft roller section substituted for the removed draft roller section, the assembling unit is mounted upon the hydraulic press. The lever 47 is in the lowermost position. The stand or carriage is now rolled toward the draft roller I38 and th lower parts 3 Hi of the clamps are arranged beneath the smooth portions M and the recesses l is are in alignment with the portions M5, Figure 22. The lever A? is now swung upwardl so that the dog 5| enters the first notch 54 from the bottom, and this raises the clamp parts [it so that the recesses H6 receive the portions M5, Figure 23. The upper clamp parts H5 are now secured to the lower clamped parts. The hydraulic press is new operated and the element A25 is moved forwardly which moves the carriages H2 inwardly. This action introduces the extension M2 into the socket I43, Figure 12. The top clamp parts H5 are then removed, and the lever A? is swung to the lowermost position, whereby the lower clamp parts I I4 assume the position shown in Figure 22. The stand or frame is now rolled from the draft roll 39.

The straightening unit is now applied to the hydraulic press, and the lever 41! is in the lowermost position, and the stand or carriage rolled toward the draft roller I38. The straightening unit passes beneath the round portions I45, Figure 18. The lever 4? is now swung up so that the dog 5| engages in the uppermost notch 56. This will bring the jaws 61 to the raised position, Figure 19, so that the notches 5-8 of the jaws are centered with respect to the round portions Hi5 and M5. The stand or carriage may be rolled slightly from the rod so that the portion we and M6 will enter the notches 58. The hydraulic press is now operated and the straightening tool '38 will engage the journal M l, bending and straightening the assembled draft roller sections. The guage is now applied to the slide 69 and its finger 86 will engage the journal M6 or other part of the draft roller, thus indicating when the same has been straightened. The draft roller may be released from clamped action, while held within the jaws 61, so that it may be turned and the straightening tool 88 again forced against the draft roller. After th straightening operation has been completed, the lever i? is again returned to the lowermost position so that the jaws 61 will be lowered with respect to the round portions M5. The stand or carriage is now rolled from the draft roller. A similar operation is repeated for inserting the extension I42 of the next draft roll section into the socket in the companion draft r011 section.

'The draft roller of a spinning frame is a precision made part and must b maintained ln accurate adjustment for the spinning frame to properly operate and produce the best results. My machine is therefore a precision machine, which will separate and assemble the draft roller sections, without injury or bending the same, and if the draft roller sections have become bent prior to their separation or assembling, the machine will restore them to the precise straight condition. My machine is brought to the spinning frame and the draft roller to be treated is removed from the bearings of the spinning frame and mounted upon the brackets secured to the frame beam. This provides the minimum transporting of the draft roller, for treatment and replacement.

The invention is in no way restricted to the general description of the same in the introductory portion of the application or to the detailed description, but resides in the various combinations and sub-combinations as defined by the claims.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.
